After successfully setting up my first Java web application on AWS EC2, I decided to take the next step in my cloud journey by integrating GitHub with AWS. In this article, I'll share my experience and what I learned during this 90-minute project.
Project Overview
This project focused on establishing a connection between a GitHub repository and AWS, setting up version control, and managing code changes effectively. It's part of a larger DevOps pipeline I'm building, which will eventually include CodeBuild, S3, CodeDeploy, and CodePipeline.
Key Components and Learning Points
Git and GitHub Setup
The first major learning was understanding Git's distributed version control system.
Setting up my local repository involved three crucial steps:
Initializing the repository with git init
Adding files to the staging area with git add
Committing changes with descriptive messages using git commit -m
Authentication and Security
One interesting challenge I encountered was GitHub's authentication system. I learned that password authentication is no longer supported (as of August 2021), and instead, I needed to use Personal Access Tokens. This taught me about modern security practices in DevOps.
To set this up, I:
Navigated to GitHub Settings > Developer settings > Personal access tokens
Generated a new token with appropriate scopes
Used this token for authentication instead of my password
The project helped me understand the Git workflow:
Making local changes to files
Staging changes with git add
Committing with meaningful messages
Pushing to GitHub using git push -u origin master
Future Pipeline Plans
This project is just the beginning. Looking ahead, I plan to implement:
AWS CodeBuild for automated building
S3 for artifact storage
CodeDeploy for automated deployment
CloudFormation for infrastructure as code
A complete CI/CD pipeline using AWS CodePipeline
Key Takeaways
Version control is fundamental to modern software development
Security best practices are crucial in DevOps
Understanding Git commands and their purposes is essential
Planning for future pipeline expansion is important
Looking Forward
This project has laid the groundwork for a more comprehensive DevOps pipeline. The next steps involve implementing automated building and deployment processes, which will further streamline the development workflow.
For those starting their DevOps journey, I recommend:
Start with basic Git commands
Understand authentication and security
Plan your pipeline architecture
Take it step by step
Remember, DevOps is a journey of continuous learning and improvement. Each component you add to your pipeline brings new challenges and learning opportunities.
